3. Study the content preferences through a second user study: A new version of ARemind (version 2.0) will be built based on the feedback from the first user study. It will include the three remote adherence assessment modules. It will be tested longitudinally for 3 weeks on 15 patients with HIV/AIDS. The patients will use Medication Event Monitoring System (MEMS) software, in the form of MEMS caps, and have weekly clinic visits with adherence counselors who will generate a composite adherence score at each visit. MEMS caps are electronic devices attached to a pill bottle which detect and record the time at which the bottles are opened and closed, using this as an estimate for the number of pills taken. These will be compared to the adherence scores from the remote adherence assessment modules. The patients will give qualitative feedback at each visit on the reminder messages to guide the design of content resistant to user fatigue.
